I signed up for GreenDimes to get rid of my junk mail. We get at least 3 pieces daily. I often wonder how in the world they got our names. We have been living here for 10 years and the person who lived her before still gets mail! In reading their blog today I found out about EarthHour. Everyone turns off their lights for one hour. Worked last year and had lots of participants. They are planning for 2008.
